Abstract
An apparatus for compensating a steering angle signal and motor angle signal of an MDPS system may include: a motor torque compensator configured to compensate for mechanical deformation; an angular speed compensator configured to compensate for a difference between a steering angle and a motor angle; a sensor characteristic compensator configured to compensate for a steering position error of the steering angle sensor; and a hysteresis compensator configured to compensate for a hysteresis characteristic of the MDPS system.
